Filed: 1971-10-23
Abstract: 1406428 Mechanical switches; latching and unlatching switches; thermal switches CREDA ELECTRIC Ltd 20 Oct 1972 [23 Oct 1971] 49343/71 Heading H1N An electric immersion heater 6 in a liquid heater 1 is controlled by a switch 7 normally biased open but capable of being latched to the closed position by a latch element 15 (a rod), switch 7 being released by a detector 19 when the liquid boils, detector 19 being submerged in the liquid in use. To close switch 7, pushbutton 12 is depressed which through tail 13 pushes plate 14 which pivots lever 9 about axis 11 which pushes spring arm 10 attached to switch 7 to depress button 8 to close switch 7. If the liquid is not boiling, detector 19 (a plate with flanges round the edge) falls under the action of gravity and pivots rod 15 about axis 18 to slide it along the arm of slot 16 in lever 9 away from axis 11 to latch lever 9 and switch 7 closed. When the liquid boils, the turbulence over heater 6 lifts detector 19 which pivots rod 15 back towards axis 11 so that it enters the arm of slot 16 at right angles to the longitudinal axis of lever 9 and releases lever 9 which is urged back to its original position by spring arm 10 releasing switch 7 to open its contacts. If it is desired to release switch 7 before the liquid boils, pushbutton 23 may be depressed which moves arm 24 to urge rod 15 towards axis 11 and into the arm shown in Fig. 2 of slot 16 to release lever 9 and hence switch 7. A safety device is provided which prevents setting of the latch and/or releases the latch if there is insufficient liquid in heater 1. This takes the form of a float 20 on an arm 21 having an angled portion 22 which engages under detector 19, as shown in Fig. 1, to prevent detector 19 falling or to raise detector 19 if it has already fallen. Alternatively instead of float 20, there may be a bimetal attached to heater 6, the other end of the bimetal co-operating with rod 15, or a spring member restrained by a low melting- point alloy fusible element. Also heater 6 may be mounted beneath the bottom 3 of heater 1. The liquid enters heater 1 through pipe 5. Heater 1 may be a domestic sink water heater, or a tea-urn, or electric kettle, &c.

Abstract: 1,115,463. Advancing mine roof supports. DOWTY MINING EQUIPMENT Ltd. Nov. 25, 1965 [Dec. 7, 1964], No.49755/64. Heading F1P. Mining apparatus comprises a series of advanceable hydraulic mine roof supports 1,2,3 (one shown), each having a first valve assembly 5, 6 operable to cause its associated support to perform an advancing operation and at least some of which having a selector valve assembly 13 which when supplied with pressure fluid through a signal line 12 from a different support is manually actuable to cause in one position conveyer advancing jacks to be operated and in a second position to cause the operation of the associated first valve assembly 5, 6. The supports having selector valve assemblies 13 act as master roof supports for slave supports disposed between adjacent master supports. In operation the selector valve assembly of the first master roof support of the series is actuated to open and hold open a valve 15. A second valve assembly 17 provided on each master support is then actuated in the next master support of the series to open a valve unit 18 and thus connect the signal line 12 leading back to the first master support to be pressurised from a main pressure line 8. On arrival at the first master roof support, the pressure in signal line 12 passes through the previously open valve 15 to a line 11 connected to the conveyer advancing jacks of the pair of slave roof supports on opposite sides of the first master roof support. When the conveyer has been fully advanced the selector valve assembly is moved to its other position thereby opening and holding open valve unit 14 and closing valve unit 15. To cause the first support to advance, the second valve assembly 17 of the second master support is again actuated to send a second pressure signal along the signal line 12 whereby a line 7 is pressurised through the previously opened valve unit 14 to cause the support to advance by appropriate operation of the first valve assembly 5, 6 as described in Patent specification 1, 023,478. When the support has satisfactorily advanced the resulting build up in support pressure opens a control valve 26 to cause pressurisation of a pilot line 27 leading to the adjacent slave supports. The slave supports not previously advanced automatically advance in turn on pressurisation of the pilot line 27. The second and subsequent master supports and the slave supports controlled thereby are advanced in a similar manner.
